Three die-hard Giants fans have contracted a sudden case of Timsanity.

The Big Blue crew — a Manhattan man and a pair of Brooklyn-bred brothers — are competing for the trademark to “Timsanity,” a phrase they hope to splash on athletic gear to capitalize on the mania surrounding new Jets QB Tim Tebow.

“For me, it’s just business,” said Frank DeGrim, 29, an East Village resident who is a manager at a hedge fund.

“When I heard he was coming to New York, I realized there’s an opportunity here,” he told The Post.

DeGrim filed his application with the US Patent and Trademark Office on March 21 — a day before Daniel and Christian Perez, a Bensonhurst-born duo.

“It’s an excellent business opportunity and it makes sense to register the mark — so it doesn’t surprise me at all that someone else had the same good idea,” DeGrim said. “Luckily for me, I just happened to have it first.”

Daniel Perez, 37, said he still likes his chances, and even offered to team up with DeGrim. “I’ll probably reach out and see what we can work out together,” he said.

Perez, who works in marketing for MTV and lives in Queens, said he and his brother root for Giants QB Eli Manning — but makes an exception for Tebow.

“I would like him to prove everybody wrong. All you hear is that he can’t play, and all you do is see him win,” he said.

Perez has also snapped up three Tebow-centric domain names, including TimsanityShop.com, TebowTimeJets.com and TimsanityOnline.com.

DeGrim — a New Jersey native who also bleeds Giants blue — has not claimed any sites, but said he’s already receiving offers from people interested in working with him.

Timsanity derives from “Linsanity,” spawned in February after the emergence of Knicks guard Jeremy Lin. There are nine Linsanity trademark applications pending — including one on behalf of Lin himself.

Experts said the Perez and DeGrim applications may not have a prayer — federal examiners may sack Timsanity because of its similarity to Linsanity.

“The typical test is sight, sound and meaning,” said trademark lawyer Kurt Anderson. “I think there’s a reasonable case to be made that one might be confused with the other.”

But Tebow may have less a leg to stand on than Lin if he chooses to oppose the trademark application.

“Timsanity can apply to any Tim,” Anderson noted.
